UNIVERSAL ANGLE-COUPLING .AND VALVE-SEAT FOR IPIPING.

Application led February 16, 1911.

T 0 all whom, it may concern Be it known that I, Henman Gr. HAAsE, acitizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented. certain new and usefulImprovements in.Universal Angle-Couplings and Valve-Seats for Piping, ofwhich the following is a specification.

My invention relates to a universal conp'ling for use in connection withpiping of every sort and provides means whereby said coupling may beutilized to form a union between two pipes extending in any relativeangular direction from ninety to one hundred and eighty degrees (00' to180).

It is also an object of my invention to provide in such angle couplinglneans for cooperation either with a ehoke'valve or cheek valve, asmaybe desired. Such an adaptation is rendered prat-t icable by reason ofthe characteristic and novel features of my universal joint, whichJfeatures will be described in detail in the specification andparticularly pointed out in the claims.

In the-drawings illustriing the application of my invention in oneform,*Figure 1 is a side elevation of thedevice having a choke valveapplied thereto and with the parts set at ninety degrees (90o). Fig. 2is a similar View in Becton. Fig. 3 is an ele\ ation showing the pinesat an obtuse angle to one another. Fig, 1 is a sectional View of theunion with the pipes in line and the check valve substituted for thechoke valve. Fig. 5 is a plan view from above of the parts shownin Fig.1 with the valve wheel omitted.`

My union comprises a pair of members 8 and 29, member 8 being` providedwith an intcriorly threaded coupling extension, as indicated at 8', forforming a connection with a pipe 9 and member Q9 beingprovided with asimilar intcriorly threaded coupling extension 30 for formingconnectionwith pipe 31. Member S is provided with an expanded port-ion 7,saidportion beingformed with an annular face 7 surrounding said expandedportion and lying in a plane angularly disposed with respect to theaxial center of opening 8 and pipe 9, the preferred angle, as shown,being forty-tive degrees.

YIn the form shown the face 7 is continued in the upwardly curvedportion 24 lhereinafter described and from there outwardly vided withSpecication of Letters Patent.

forms an integral part of member S and intersects said member atan angleof fortytve degrees to the axial center of coupling extension S and pipef), that is, so the face of said diaphragm will lie in a plane parallelto the plane of the face of the member. The member Q9 is provided withan expanded portion 21 having an annular face 9.1', said face 21 beingin the plane at an angle of forty-five degrees to the axial center ofthreaded coupling extension 30 and pipe 31. Face 21 has an upwardlycurved portion forming a seat 23 corresponding with the portion 24 offace T. the respective faces 011 expanded portions 7 and 21 beingadapted to cooperate in any relative position thereof to form a tightunion.

The diaphragm 10 is' provided centrally thereof with a suitable Vopening11, said openingl being provided at the top with an integral ring orl'iange 12 forming a seat for a check valve 13, as shown in Fig. 4, or achoke valve 14, as shown in Fig. Q. Sets of lugs 15 and 16,respectively, to which the check valve 13 may be pivoted, as at 17, whendesired, are provided on the web 10, but itis to be understood thatneither the check valve nor the choke valve will necessarily have to beused with my device, which may be used merely for the purpose of form--ing angle unions, as desired.

The. member 7 is provided with an annular outwardly extending iangc 18in the plane of the web 10 adapted to coperate with an inwardlyextending annular flange 19 on the interiorly threaded coupling ring Q0by means of which an upper member 21 is secured to the base member 7,said upper member being provided with threaded annular surface 22 forthat p lose and also with a milled seat 23 adapted to co'rperate with acurved portion Q4 extending around the top of the web 10 the surface. ofsaid curved portion being correspondingly milled so as to enter exactlyinto and coincide with the surface of the seat 23. If desired, a packingring may be used between the flange 18 and the cooperating face Q5 ofthe member 21, but if theI cooperating membersure properly milled atight union will be effected without the use of any packing material, orat. mosty a little graphite or .similar sul stance. The ring 20 is shownas being profaces Q6 and notches 27 to adapt upon the surface of adiaphragm l() which the same to the use of plumbing toolsl of ordinaryconstruction. The contracted p0rtion 8 of the base'7 is also hexagonallyformed with faces 28 for the same purpose.

Centrally disposed on the member 2l a second diminished extension 33 maybe provided having a threaded opening 34 for receiving a correspondinglythreaded portion of the valve stem 35 carrying the choke Through its useany form' of ofset in which the pipes make any desired or necessaryangle not less than ninety degrees (90) can readily be effected. It canbe used either with or Without the choke valve or the cheek valve, butit is an especial feature of my invention that it provides a seat foreither of said valves capable of use in a straight run of pipe. It isalso a feature of my invention that the parts of the valve, both stemand seat, are rendered easily accessible for the purpose of truing thesurfaces thereof or remedying other defects.

I claim: p

1. A universal pipe iitting comprising two members, each of said membersbeing pr`ovided with an expanded portion having an annular face, saidfaces being adapted to cooperate in any relative position thereof toform a union, a coupling extension formed on each member at an angle offorty-live degrees (45) with the'plane of the face on said member, adiaphragm forming an in.

tegral part of one member having its tace parallel with the plane of theface of .said

member and having therein a centrally dis-l posed opening, an integralvalve seat surrounding said opening and extended outwardly therefromtoward said other momber, means on said diaphragxn'adapted to pivotallyconnect a check valve therewith to coperate with said valve seat, andmeans to secure saitl faces in adjustable coperat-ive relation.

2. A universal pipe fitting comprising two members, each of said membersbeing provided with an expanded portion having an annular face,'saidfaces being adapted to cooperate in any relative posltion thereof toform a union, a coupling extension formed on each member at an angle tothe plane of the face on said member, a diaphragm forming an integralpart of one member having its face parallel with the plane of the faceof said member and having therein a centrallydisposed opening, a vvalveseat surrounding said opening and extended outwardly therefrom towardsaid other member, means on said diaphragm adapted to pivotally connecta check valve therewith for eoperationwith said valve scat, and meanscarried by the other member for securing a choke valve in position toeoperate with said valve ser?.v l

3. A universal pipe fitting comprising tWo members,l each of saidmembers being provvided. with an expanded portion having an annularface, said faces being adapted to cooperate in an, relative positionthereof Ito form a union, a coupling extension formed on each member atan angle to theplane of the face on said member, a diaphragm forming anintegral part of one member having its face parallel with the plane ofthe face of said member and having therein a centrally disposed opening,an integral valve seat surrounding said opening and extended outwardly'therefrom toward said other member, means on said diaphragm at each sideof said opening adapted to pivotally connect a check valve therewith tocoporate with said valve seat when the coupling eX- tensions form eithera straight run or a rigid-angled bend.

In testimony whereof I have affixed my signature in presence of twowitnesses.
